Created by the combination of thin film monograin photovoltaic CZTS technology embedded into polymers to satisfy the end-user’s needs of very high degree of flexibility and durability combined with superior aesthetic performance.
Conceived by the integration of conventional thin film photovoltaic CZTS technology onto steel substrates to satisfy end-user’s needs of high degree of mechanical flexibility combined with excellent potential for high energy density applications.

|Sustainability & recyclability||Energy payback time less than 1 year and ≥ 85% recycling rate||Energy payback time of 0.5 years and ≥ 85% recyclability||WP5|
This approach will be reinforced by the development of a product integrated methodology capable to combine technical, environmental and socio-economic aspects in a full LCA and LCC. To reach this challenge, this main goal is divided into several specific objectives (SO) embedded in a tailored Work Plan:
To develop and test 2 enhanced configurations of CZTS modules conceived by the perfect combination of earth-abundant materials to demonstrate the fulfilment of KPIs directly linked with the technological competitiveness of the technology: Efficiency (20%), high-stability and lifetime (>35 years; 95%); reliability and reproducibility (less than 10% variation in key parameters); recyclability (85%) by the end of the project.
To apply a set of cost reduction strategies to achieve a highly competitive manufacturing cost target of <40 c€/Wp (polymer and steel substrate configurations). Both approaches will guarantee reducing by 20% the current manufacturing costs of competing thin-film technologies.
To assembly and test 4 module prototypes, as a full system, in 2 Business Cases where the role of PV technologies is considered vital for the final products of the end-users: AYESA as construction and engineering firm expert in BIPV and KWS as urban furniture manufacturer expert in PIPV. This approach will allow us to demonstrate technical feasibility through an exhaustive monitoring and assessment of selected KPIs in a relevant environment.
To introduce novel circular economy strategies to ensure a high-recycling target (≥ 85%) that guarantee the development of a sustainable PV solutions and to demonstrate its environmental, social and economic impact by the development of a full LCA and LCC.
To boost the European PV industry through the commitment of substantial investments in manufacturing plants especially in the cell/module assembly stages. To that end, it is needed to ensure its long-lasting sustainability, minimising the dependence of non-European raw materials thanks to promotion of local earth-abundant materials. The CUSTOM-ART project will provide an excellent framework to convert the knowledge of the centres of excellence in tangible products, services and innovations by the industry players.
To update and refine the current feasibility study and business plan as a “strategic tool” to get a smooth market penetration and proper orientation of the future products and services in 2024. This plan will require the generation of profitable business models, the application of an IP and knowledge management strategy and the definition of finance and investment plans, among others.
